[[AppleDouble]] is one of the systems used to store the [[Resource Fork]] of Macintosh files on filesystems not natively supporting it, something which became necessary when Apple moved to Unix-based operating systems instead of "classic" MacOS. [[AppleSingle]] is an alternative format to accomplish the same end, combining all the forks plus a metadata header in one file instead of keeping separate files like AppleDouble. While both AppleSingle and AppleDouble were introduced for use with early Unix-based Apple systems, AppleDouble survived as the main method of storing files with resource forks on OS X systems if a filesystem is used that doesn't directly support such forks.

The AppleDouble format keeps the data fork of the file in its original format and filename (this is the main file, as used by non-Mac operating systems, and for many file formats, the only one that matters), and creates a second file with the resource fork as well as Finder metadata. The second file has the filename of the main file with "._" (a dot and an underscore) preceding it. If it was encoded for transmission, [[Base64]] was generally used.

[[BLEND]] is a scene description format associated with the ''[http://www.blender.org Blender]'' 3d modeling and animation software by the Blender Foundation.

The blend file format is not a true file interchange format, rather it dumps internal data structures from directly from memory to disk. A blend file’s structure may therefore be unique to each version of Blender. Despite this, blend files are both [http://www.blendernation.com/2008/12/01/blender-dna-rna-and-backward-compatibility/ backward and forward compatible] between versions, and between different hardware and operating systems. This is made possible by the addition of metadata, known as [http://wiki.blender.org/index.php/Dev:Source/Architecture/SDNA_Notes Struct DNA], that allows conversion when loading the file.

Since no standard blend file format specification exists, the Blender source code must serve as the definitive specification.
